Episode 20 — Wet Mars / White Mars

After a break (thanks to a surge of activity at work and home), podcasts are back — this episode, with a two-threaded take on recent events on the red planet.

There have been a number of hypotheses / theories trotted out over the years in an effort to explain the role that water has played (if any) in the history of Mars. Some of them have had a scientific basis, others have been more culturally based. Currently, the crop has really been thinned down to just two main theories, or at least, families of theories.

Tune in to hear both the human and geological history of water on Mars, and a bit of background on the argument you’ll hear subtly running in the background in related press releases.
